The Italian's side beat West Brom 1-0 thanks to Edin Dzeko's volley, but the manager believes it could have had far more goals if its strikers had not wasted so many chances.

Manchester City manager Roberto Mancini has once again expressed his irritation at his side’s inability to take its chances and make its dominance of games count.

The FA Cup finalist beat West Brom 1-0 at the Etihad Stadium thanks to a volley from Edin Dzeko, and the Italian repeated his message from earlier this week that the team’s poor finishing keeps letting it down as it failed to extend its lead against the Baggies.

“I’m frustrated because it is almost impossible to miss all these chances,” he told ESPN after the game. “When you have six or seven clear chances, you should score.

“In the first half, they started better than us for the first 10 minutes, but we’re missing I don’t know how many chances.”

Mancini made eight changes for the game, with one eye on the FA Cup final against Wigan on Saturday, and he praised his players for coming in and performing despite a lack of match practice.

“It was a difficult game,” he said. “We knew it would be before the game, because we changed [eight] players, and it’s difficult.

“Also, the players did everything to win this game, so it was an important win. It was difficult for Micah [Richards] and [Edin] Dzeko as they haven’t played for a long time, so it’s not easy.”

City's cup final opponent lost 3-2 to Swansea in its crunch Premier League match on Tuesday night, but Mancini is not expecting the Latics to be demoralized when they make the trip to Wembley.

He added: “They still have a chance, they have another two games and they will be looking to avoid relegation. They have more chances in the next two games.

“The final is the final, it is not important for the Premier League, and I think they’ll play at 100 percent and be very strong.”
